76 Mr. "W. R. Ogilvie-Grant on the Birds collected 



The Mosqvie-S wallows usually arrive in large flocks early 

 in March, hut a few have heen seen as early as January. 

 They leave again hetween the middle of September and 

 the end of October, but some linger on into jNoveml)er and 

 December, the latest date being the 22nd of the last- 

 named month. 



Possibly these very late birds are those which have nested 

 only a little further north. Prior to migration they settle in 

 vast numbers on telegraph-wires and other suitable perching- 

 places in the same manner as the otljer Swallows. 



Building begins at the end of April, and nests containing 

 eggs in all stages of incubation, and in a few cases young 

 birds, were found on June 3rd. 



Eggs vary in length from 85 to '09 and in breadth from 

 •C2 to "58 ; they average '77 x GO.

V. — Notes on the Birds collected l)y the B.O.U. Expedition 

 to Dutch New Guinea. By W. 11. Ogilvie-Gkant, 

 F.Z.S., M. B.O.U. 



The following account of the birds brought home from 

 New Guinea by the B.O.U. Expedition has been reprinted, 

 by the kind permission of Messrs. Smith, Elder & Co., 

 from the Appendix A to Mr. A. F. K. VVollaston's volume, 

 ' Pygmies and Papuans,' which contains the official account 

 of the Expedition. As it was thought that this account 

 might not come under the notice of all the Members of tlie 

 Union, it has been considered advisable by the Editor to 

 reproduce it in the 'Ibis' Mith a few additional notes and 

 slight alterations. When Mr. Wollaston, who is accom- 

 panied by Mr. C. Boden Kloss and fire trained Dyaks, 

 returns with large additional collections from the second 

 Expedition, it is intended to draw up a complete account
